An international collaboration at GSI/FAIR in Germany reports the first experimental evidence that an eta-prime meson can be bound inside a carbon-11 nucleus, with data hinting that the meson loses mass in nuclear matter.

The $3 million prize recognizes three generations of experiments at CERN, Brookhaven, and Fermilab that measured the muon's magnetic moment to 127 parts per billion, sharpening a long-standing test of the Standard Model.

MicroBooNE and KATRIN independently close the door on the light sterile neutrino, while China's JUNO detector surpasses 50 years of precision in just 59 days.

The SuperCDMS experiment at SNOLAB has cooled its 24 detectors to near absolute zero, preparing to probe an unexplored low-mass dark matter range within the year.

A SQUID-based detector that tunes itself electronically rather than mechanically achieved a 20-fold speedup in scanning for dark photon dark matter, covering a 22 MHz frequency range in three days.

A University of Bath researcher used the Lean 4 theorem prover to formalize a 2006 particle physics paper and discovered its central stability theorem is false, marking the first time formal verification has uncovered a substantive error in published physics research.

Back-to-back results at Moriond 2026 confirm the most massive bound state ever observed and resolve a two-decade search for the doubly charmed baryon.

The BASE experiment at CERN successfully moved 92 antiprotons in a portable cryogenic trap across the laboratory's campus, demonstrating that antimatter can survive road transport and paving the way for precision measurements at facilities across Europe.

The CMS Collaboration at CERN has detected wakes left by quarks speeding through quark-gluon plasma, providing the first direct evidence that the matter filling the universe in its first microseconds behaved as a nearly perfect liquid rather than a gas of free particles.
